invention may be carried into effect, like characters of reference indicating like parts, and in which-- Figure l. is a sectional elevation on the line A B B A of Fig. 9. and shows the adjusting valve in such a position that no motive fluid Whatever is capable of passing into the engine cylinder. Fig. 2 is a sectional elevation taken on the line C C of Fig. 1, part of the main valve being shown complete for the purpose of showing certain ports. Fig. 3 is an outside elevation of our improved engine looking in the direction of the arrow D. Fig. 4 is an out-side elevation of the adjusting valve, the main valve being shown in dotted lines for the purpose of showing the relation of the adjusting valve to the main valve.v Fig. 5 is a sectional view of the adjusting valve taken on the line E E of Fig-4. Figs. Gel?) inclusive are part sections taken on the line A B B A of F ig. 2 to show the adjusting valve and the main valve in various relative positions. Fig. G shows'the adjusting valve and the main valve in such relative positions as to allow a charge of compressed motive fluid to be passed into the engine cylinder. Fig. 7 shows the adjusting valve turned to another positiomwherein the supply of compressed motive fluid used for starting up is discontinued While at the same time the charge of combustible mixture is allowed to pass into the engine cylinder. Fig. 8 shows the adjusting valve in the same relative position in Fig. G, namely, the

starting up posit-ion, but the main valve is shown turned to a new position with respect to the adjusting valve and the exhaust. of the starting up chai/'ge is just about to commence. Fig. 9 shows the adjusting valve turned to the normal working position as shown in Fig. 7, the main valve now being turned to such a position as to permit. of the cylinder products being exhausted Fig. l() shows the adjusting valve placed into such a position Within the man. valve as to permit a Charge o compressed motive fluid being passed int the engine cylinder so as to cause the engine to turn in the to Fig. 7. the adjusting valve being adjusted topernnt of the c running in the reverse direction. F1; l2 andi?, are views snowing how the retin valve may ne Fig. 1l is a view similar WormY wheel l d ss Lhe cut-off valve While the adjust4 ing velveis used to determine the point of the exhaust.

ln carrying the present invention into effect in the preferred mnner, at the upper end of the cylinder l we provide :i housing 2 the cylinder and housing being water jacheted as illustrated in Figs. l .find 2.

3 indicates the main valve which is preferably cylindrical in form audit is mounted Within the said housing 2 and adapted to be continuously rotated, While the. engine` is running, by eny'suiteble means. As shown in 2, one end of the main valve 3 .may conveniently be carried through the end of the housing;r 2 and lieve secured thereon e which is arranged to be in mesh with a worm 5 carried'upon a spindle 6 which mounted in suitable bearings and is driven in any suitable manner from the c rzmlc shaft of the engine or any other revolving part'. ,Of course in place of the worm wheel 4 we muy, if we so desire7 provide' a pinion secured upon the' end of the main valve for the purpose of rotating the same, and in such a case the Suid pinion would be driven by suitable gearing.

It is to be pointed out that we do not in tend the above to'indi'oate the only errungeinent we muy adopt Aby which to rotate the mein vulve 3, for we muy, if we so desire, instead of allowing one end of the main vulve 3 to project through the end of the housii'ig 2,' arrange e. shaft fixed to the. Said 'vulve 3, and allow such shaft to project through the end of the housing and provide on this shaft suitable means by which the valve 3 be rotated.

'i' is e. passageway arranged in the housing 2, by ineens of which the supply of combustible mixture is conducted Jfrom the induction pipe. to the main vulve 3, the said induction pipe being secured to the housing by a flange which is secured in position on the facing 8 by suitable means. 9 is a pas sageway provided lin the housing', by means of which the exhaust gases are conducted away .from the engine, 10 being` the facing against whiclV the flange o the exhaust pipe vmuy be convenient-ly secured. Also if we So desire we muy provide suitable undv 'wel.lknown means by the eid of which the main valve 3 kept in place within the housing 2 ann these means, if desirable muy be made resilient .fis by the use of n spring. Such n provision es this, being of e welllsnown character, is not illustrated.

Nithin the valve 3 we locate a. member .l2 which member is adapted to be rotated. :is desired he purpose of admitting motive fluid from the space i3 Yformed as hercinafter described between the 'valve 3 and the valve 12, to the engine cylinder or for enebling exhaust gases to pass from the engine cylinder into the space 11i also formel between the valve member 3 and the valve meniber lil and from Vthence to the. exhaust passageway 9 previously mentioned. This member which we locate `within the cylindrical valve, we prefer to cull the'controller or adjuster.

Referring now more particularly to the cylindrical Valve member 3 We preferably provide it with a plurality of slots or ports 11 errunged'in its periphery and these slots ere oi" sullicient length und breadth as to allow of the necessary quanti y of mixture passing into the engine cylinder at the desired speed, ,and the arrangement of the slots is such that when one slot is in comwhichn'iotire fluid is led up to the vulve member 3. another of the seid slots 11 is in such a position es to allow a How of gas to teilte place from the interior of the cylindrie-al valve member 3 into the engine cylinder. Further as will be seen this cylindrical member 3 will be acted upon by the pressure ofthe gas Within the engine cylinder and we preferably arrange means by which the.- suid cylindrical member is ulwnys kept down on its seat and in the region of the port'connmn'iicating with the engine cylinder, The 'precise manner'in WhiCh thib cfi'eoted will be described hereafter. Again, if. we so prefer, we muy provide' a plurality of cireiuz'iferential grooves on the "indruk-,xl member, euch of these grooves l, .lng adopted to contain u. suitable, pecking r uf by menus oi which leakage along,r the outer periphery of the cylindrical vulve member and the Sides of the` housing' in which it is locuted, is prevented7 and since this particular method of preventing leakage is so well-known, it has not been'thought necessary to illustrate it in the drawingsL The controller ,12 above mentioned we prefer to malte cylindrical in form and ore end '15 is adapted to poss through the. outer end of the vulve 3 and to be operated by menus of u suitable handle for the purpose of rotatine,r the controller within the cylindrical vulve member te any desiredposition. In the accompanying drawings we have shown the adjuster oir-controller 152, es being open ated by i'ociins of a rech 16 suitably supported und operated within guides 17, and being in engagement with a pinion 18 secured upon the end 15 oi" the adjuster so that. an adjustment of the melf will serve to rol-ate the vulve l2, but any other well-known means muy be adopted forbringing about the necessary rotation. On the surface of `this controller We provide e plurality of recesses. 'lhe recess 19 serves to provide a space 13 bei. reen the innef.1 surface of the vulve 3 und the outer surface of the vulve 12 and tlu ugh this space the charge of combustible mixture is adapted to pass.A This recess 19 i is of such :i length eircumferentially es to muniention with the passageway 7 through` .1.1.11 ...i U V 1.1 I. 1 e n E.. l .1 1 I n.. 1 1. 1 H v ,.1 L l ..11 n...
